The organolanthanide fluoride [(η5-C5H41Bu)2Sm(μ-F))]3 (1) was generated by oxidation of [(η5-C5H41Bu)2Sm(THF)2] with Me3SnF. The X-ray structural analysis of 1 showed the trimeric compound to be monoclinic space group C2/c, Z = 4, with a = 18444.6(6), b = 1537.5(3), c = 1871.2(9)pm, β = 104.55(4)° and Dcalc = 1.597 g cm3. The structure was solved from 3942 observed reflections with Fo > 4σ(Fo) and

氟化物[(η 5 -C 5 H ^ 4 1卜)2 SM(μ -F))] 3(1)用的氧化产生的[(η 5 -C 5 H ^ 4 1卜)2的Sm(THF)2 ]与我3 SnF。的X射线结构分析1表明三聚体化合物是单斜晶,空间群C ^ 2 / ç,Ž = 4,用一个= 18444.6(6),b = 1537.5(3),C ^= 1871.2(9)pm,β = 104.55(4)°,D calc = 1.597 g cm 3。该结构是从3942个观测到的反射中解析出来的,其中F o > 4σ(F o),并细化为最终R = 0.0735。
